North American Indian Artifact?

[Thunderchild]

I found this object while relic hunting in Virginia.  Looks like the biggest arrowhead I've ever seen.  I know diddly about native American stone tools,points etc.  Any help IDing it  would be appreciated.  Thanks.

Sorry, not an Arrowhead and not an artifact. Wrong material and no evidence of ever being worked by man.
